The vegetal pole of a frog zygote differs from the animal pole in that the vegetal pole has a higher concentration of yolk.

After the fertilisation of the egg by the sperm in a frog, three regions are formed in the zygote. These are:

  1. Upper animal hemisphere or upper animal pole which shows pigmentation.
  2. The grey crescent which is a small area with almost no pigmentation. It is present in between the upper animal pole and the lower vegetal pole.
  3. Lower animal hemisphere or lower vegetal pole which is white in color.

Thus, the vegetal pole of a frog zygote differs from the animal pole in that the vegetal pole has a higher concentration of yolk.

Answer:

sour, corrosive

Explanation:

An acid is a substance that donates hydrogen ions. Because of this, in an acidic solution  there are more hydrogen ions than hydroxide ions. This means the more acidic a food is, the more hydrogen ions are available to trigger the sour taste receptors. A base is a substance that accepts hydrogen ions.

Answer:

The vision remains unaffected.

Rods and cones are two types of photo receptor cells present in the organism. Cone cell helps in the visualization of color whereas rod cells are involved in the light intensity.

True or false? in host-versus-graft rejection, the recipient recognizes the donor tissue as foreign and rejects the transplant;
snow_tiger [21]
The statements above are true;
In a host-versus-graft rejection the recipient's immune system recognizes the donor's tissue as foreign and rejects the transplant. On the other hand, in a graft-versus-host rejection, the donor tissue recognizes the recipient's tissue as foreign and the transplant rejects the recipient, causing destruction of the recipient's tissue and possibly death. Its important also to note that there are two types of rejection, the acute rejection, where the rejection of transplanted tissue that occurs several weeks after transplant. it is delayed hypersensitivity reaction, and the chronic rejection is a rejection of transplanted tissue that can occur at a late time. Immune complexes form in the arteries supplying the graft, choking off the blood supply and the tissue is rejected.
